Title: Photoreptive device
Inventor: WARASHINA SADAHISA
IPC: H01L31/02
Filed: 2000-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a photoreceptive device in which a signal can be transmitted at a high rate, using a simple arrangement. SOLUTION: Wiring WA creeps linearly on an exposed surface ES and extends passing through a mount member MT to the side surface SS of the mount member MT, perpendicular to the exposed surface ES. The anode electrode AE of a rear surface irradiation photodiode PD is fixed to the side surface SS, such that it is located on the extension of the wiring WA, and the anode electrode AE is connected electrically with the wiring WA. Since the wiring WA extends linearly even though it has a simple structure for fixing the photodiode PD to the mount member MT, high rate signal transmission can be realized.
